UNlTED STATES PATENT curios PRESSURE HAND OILER Arthur E. Straub, Rew, Pa. Application July 9, 1932, Serial No. 621,702

My invention relates 7 Claims.

to improvements in hand invention is to provide an efficient and easily operated device of this kind, havin g a novel arrangement of parts and elements, promoting easy assembly and repair.

purposes of illustration embodiment of the inve In the drawing I have shown a preferred ntion.

Figure 1 is a general vertical transverse sectional view through the embodiment.

Figure 2 is a horizontal sectional View taken through a portion of the device showing the construction of the nozzle valve mechanism.

Referring in detail to the drawing, wherein like numerals refer to like parts throughout the same, the numeral 5 bcdiment which compr generally designates the emises a vertical cylindrical casing 6 having an inset flange 7 on its upper end on which is forme d an exteriorly threaded annulus 8, with which is adapted to be threadedly mounted the spherical segmental top 9.

One side of the casing 6 is thickened and enlarged as indicated at vertical channel 11 therein.

10 and provided with a The bottom 12 of the enlargement 10 is somewhat spaced about the bottom 13 of the casing 6 so that the lower end of the channel 11 communicates with the interior of the casing. The

enlargement 10 has at its upper end and radially inwardly projecting into the container a rounded enlargement 14 through which is transversely journaled a tapered cock 15 which is rotatably secured by means of a washer and nut structure 16 at one end thereof.

The other end of the 0 disk 16 which has an ock 15 is provided with a eccentrically located pin 17 with which is rockably connected a connecting rod 18 for operating the cock. The cock is provided with a transverse passage 19.

Adjacent the enlarged portion 14 and projecting radially outwardly zle 20 provided on its 0 21 which may be so thereon. The nozzle is tudinally extending passage of the casing 6 is the nozuter end with a spray jet rew-threadedly mounted provided with the longi- 22 which communicates with the chamber in which the cock 15 works. The upper end of the channel 11 is radially inwardly and upwardly extended until it reaches a level of alignment with the passage 22,

where it is radially outwardly directed into the cock chamber, so that aligned with and regi its opening thereinto is stered with the opposed opening of the channel 22. Rotating the cook 15 by means of the operating lever 18 will bring about the alignment and registry of the passage 19 in the cock with the openings of the channels 11 and 22 so as to permit passage of fluid, such as ordinary lubricating oil, from the interior of the casing 6 through the nozzle and jet 21.

Means for operating the operating rod 18 comprises the slide bar 23 which is slidably mounted through a stufiing box 24 located at a point approximately diametrically opposite the nozzle 20. The stuffing box comprises an adapter 25 threaded into the wall of the container and provided at its inward end with an opening 26 for slidably and snugly receiving the rod 23. Into this is threaded a ferrule 27 which engages the packing 28 for making a leak-proof engagement of the parts. The bar 23 has circumposed thereon a spring 28 which operates between the ferrule 27 and the thumb knob 29 on the outward end of the bar 23. This arrangement of the spring normally operates the bar 23 so that the cock will be maintained in the closed position.

Under the thumb operated valve opener 29 there is located a vertically disposed handle 30. The handle 30 and the thumb operated member 29 are so located in cor-elation that the device may be easily carried about and manipulated and directed, and at the same time be always under operating control with respect to the opening and closing of the cook 15.

The top 9 seats upon an annular packing washer 31 which rests upon the upper end of the casing 6. The top 9 is provided in one side with a clean-out or filling threaded plug 32 for enabling filling the device with lubricant and the like, and cleaning the same when necessary.

For generating pressure in the casing 6 for forcing out the lubricating oil or the like when the cock 15 is operated into the open position, so as to spray such fluid, pressure generating means is carried by the top 9. The pressure generating means comprises an open-top, vertically elongated hollow cylinder 33 which is threaded into an opening 34 in the middle part of the cap 9. In this connection a packing washer 35 is utilized to preserve the pressure-tight condition of the casing. The bottom of the cylinder 33 is closed except for a threaded opening 36 centrally thereof which communicates with a valve chamber 37 105 in a depending neck 38. Within the valve chamber 37 is a spring-urged ball check valve 39 which seats in the upper end of the chamber normally to close the passage of fluid into the cylinder 33.

Threaded into the upper end of the cylinder 1110 33 is a threaded plug 40 which has a recessed underside to coact with an irregularly shaped packing 41 which rests upon a threaded body 42. The members 40, 41 and 42 are provided with a registering opening therethrough in which is slidably and closely disposed a piston rod 43 which has threaded on its lower end portion a metallic disk 44, a metal or rubber cap 45 for enabling the production of fluid pressure upon pushing the rod into the cylinder 33. The upper end of the rod is provided with a handle 46.

Though I have shown and described herein a preferred embodiment of the invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in material and structure and arrangement of parts, within the spirit of the invention and the scope of the subjoined claims.
